TS Forecast Factory Tool

The TS Forecast Factory tool provides forecasts from groups of either ARIMA or ETS models for a user-specified number of future periods. In addition, upper and lower confidence interval bounds are provided for two different user-specified percentage confidence levels. For each confidence level, the expected probability that the true value will fall within the provided bounds corresponds to the confidence level percentage.

This tool uses the R programming language. Go to Options > Download Predictive Tools to install R and the packages used by the R Tool.

Input

Configure the tool

The field name for the point forecast: Specify a name for the column that will contain the point forecasts for the groups. (Point forecasts are the reported value of the forecast, in contrast to the confidence intervals.)

The percentage value of the larger confidence interval: This value can range from 1 to 99. Common values are 95 or 99 percent. For example, a 95 percent confidence interval would mean that there is a 95% probability that the true value will be within the interval.

The percentage value of the smaller confidence interval: This value can range from 1 to 99. Common values are 80 or 90 percent.

The number of future periods to forecast (assuming no covariates in model): Specify the number of periods to forecast.
